摘　　要：为更全面、准确地描述配电网络和电力负荷的结构,已有文献提出了考虑配电网支路的综合负荷模型。文中分析了该模型参数的可辨识性,获得明确结论,即已知配电电抗或电阻、或者已知两者之比时,参数是可辨识的。通过仿真算例和实测数据验证了理论分析结果的正确性。In order to more comprehensively and accurately represent the load area with a distribution network, a synthetic load model （SLM） has been reported in literature. This paper presents an analysis of the identifiability of the SLM and the conclusion that, if the distribution reactance or resistance or the ratio of one to the other is known, the parameters are identifiable. The tests on a simulation system and a practical system have verified the theoretical results.
